DYDX plans to deploy the public testnet of its Cosmos-based blockchain next week, having completed Milestone 4 and having over 40 validators running its software. Connecting wallets, reading the order book, making market orders, and accessing account information will all be tested on the testnet. Currently, it will only function with Bitcoin and Ethereum markets, but DYDX intends to expand its network to include over 30 additional markets in the future. Milestone 5 will be completed with the introduction of the mainnet in September. DYDX recorded $466.3 billion in total transaction volume in 2022, a 140% increase over the previous year.
